I love Imperial beard, which is also known as Friendly Mutton Chops. Take this for an example:

Here is a another gentleman that more people can relate to:
General Ambrose Burnside (United States)

I love to wear it sometimes, maybe once a year for a few days? Where I come from people don't have those beard styles anymore. Everyone relates them to the old times and that British people loved them back then.
On an upcoming visit to Edinburgh,Scotland and London,England I'd love to wear my beard that way. I find that beard extremely graceful. Is there any general disliking associated with it in the UK? I wouldn't wish to become a laughing stock or to draw some ire/snark. I'm in my early thirties and don't look even remotely as good as those gentlemen in the pictures.
I'm perfectly fine with a glance or two, and even a small talk about it if somebody likes to. I just don't wish to attract too much negative attention for all the wrong reasons.
